Survey on Macro Invertebrates of Hajati Spring, Fars-West, Kazerun

Background and aim: In order to diagnosis of composition, distribution and abundance of Macrobenthic invertebrates’ fauna of Hajati Spring at Kezerun, Fars south-west of Iran, benthic sampling was conducted from March, ۲۰۱۸ to February, ۲۰۱۹. Materials and Methods: The samples were collected from five different stations along the river. Three phyla of macrobenthic invertebrates were encountered in the river. Results: They were Arthropoda, represented by eight genera, Chironomus sp., Tipula sp. and Odontomiya sp. (Diptera), Epitheca sp.(Odonata), Centroptilum sp. (Ephemeroptera), Hydrobius sp. and Hydrochara sp. (Coleoptera); Annelida represented by one genera, Uncinais sp. (Haplotaxida) and Mollusca represented by one genera including Melanopsis sp.( Sorbeoconcha), Arthropoda dominated the macrobenthic invertebrates with a abundance of ۶۵.۶% while Annelida had the least abundance, ۶.۴% by number. The abundance of Mollusca was ۲۸% by number. Also the abundance and diversity of Arthropoda was more than Mollusca and Annelida. Conclusion: One-way ANOVA showed that there was a significant relationship between collected samples and seasons (P<۰.۰۵) while such a relationship was not established between collected samples and stations (P>۰.۰۵).
